Power Supply

Before powering on the power supply, please check the power input to ensure proper grounding
of the power supply system. The input source for the switch should be reliable and secure; a
voltage adaptor can be used if necessary. The building's circuit protection system should
include in the circuit a fuse or circuit-breaker of no greater than 240 V, 5A. It is recommended
to use a UPS to supply more reliable power.
Caution!
1. Improper power supply system grounding, extreme fluctuation of the input source, and
transients (or spikes) can result in larger error rate, or even hardware damage!
2. Disconnect power supply cords before servicing!

Preventing Electrostatic Discharge Damage

Electro Static Discharges (ESD) can cause damage to internal circuits, even the entire switch.
Follow these guidelines for avoiding ESD damage:
Ensure proper earth grounding of the device;
Perform regular cleaning to reduce dust;
Maintain proper temperature and humidity;
Always wear an ESD wrist strap and antistatic uniform when in contact with circuit
boards.

Anti-interference

All sources of interference, whether from the device/system itself or the outside environment,
will affect operations in various ways, such as capacitive coupling, inductive coupling,
electromagnetic radiation, common impedance (including the grounding system) and
cables/lines (power cables, signal lines, and output lines). The following should be noted:
Precautions should be taken to prevent power source interruptions;
Provide the system with a dedicated grounding, rather than sharing the grounding with
the electronic equipment or lightning protection devices;
Keep away from high power radio transmitters, radar transmitters, and high frequency
strong circuit devices;
Provide electromagnetic shielding if necessary.
